摘要

摘要: 针对水泥土搅拌法处理连云港海相软土出现可溶盐对水泥土腐蚀而产生强度劣化问题，研究了掺入偏高岭土的水泥土抗腐蚀性能。试验结果表明：偏高岭土能促进水泥土的水化反应和火山灰反应，显著提高水泥土强度，并得到了水泥土的偏高岭土最佳掺入比。研究成果为水泥海相土力学性能改良理论及海相软土水泥土搅拌法加固设计提供依据。

Abstract: According to the strength degradation problems caused by corrosion of cement-soil by soluble salts when the marine soft soil in Lianyungang area is improved by means of the cement-soil mixing method, the effect of metakaolin on the corrosion resistance of soil-cement is investigated. The results indicate that the metakaolin can increase hydration reaction and pozzolanic reaction of cement-soil to obviously improve is strength, and the best mixing ratio of metakaolin of cement-soil is obtained. The results provide a basis for the improvement of theory of mechanical properties of cement marine soil and the reinforcement design of marine soft soil by use of the cement-soil mixing method.
